RADIATOR.

SPECIFICATION forming part of Letters Patent No. 365,758, dated June 28,188?,

Application filed August 19, 1885. Serial No. 174,809.

To (tZZ whom it may concern.-

Be it known that I, FRANZ P. H. PnoX, of

Terre Haute, in the county of Vigo and State of Indiana, have invented anew and Improved Radiator, of which the following is afull, clear andexact description.

My invention relates to an improvement in that class of radiators inwhich steam is admitted to a hollow base upon which are mounted a seriesof vertical twin-pipes,which communicate with the interior of the base.

The objects of my improvement are; first, to so construct the base thatall condensewater from the steam shall be quickly and thoroughly drainedfrom the steam-ehamber and the pipes mounted thereon, thereby insuringan unobstructed and noiseless circulation of steam; and, second, toprovide means whereby circulation of steam may be discontinued in aportion of the radiator without interfering with the operation of theremaining active portion, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a vertical sectional elevation of a portion of my improvedform of radiator;

series of twin-pipes, c d, d e, and e c, the upper ends of each pair ofpipes being united by a half-turn coupling, (not shown,) thus forming acontinuous passage between adjacent chambers.

Steam is admitted to the chamber a from the steam-pipe l3, and passes inthe direction of Tubes i't'lead from the under side of each of thechambers above named into cups k k, that rise .within the water-chamber0, formed in the base A, below the chambers a a b b, so that (No model.)

all water condensed in any of the upper chambers or in the pipes willeventually run into the lower chamber, 0, a water-seal being, however,formed beneath each steam-chamber by the water held by the cups k k, andany excess of water over and above the amount held by the cups 7a 7:will run back to the boiler, or to such other receptacle as may beemployed through the pipe D.

In mild weather, when the full power of the radiator is not required toheat the apartment, it is desirable that a portion of theradiatingsurface should be cut off; and to this end I provide a cut-offvalve for the series of pipes marked (1, or the valve can be applied tothe pipes e of the chamber 1); or, if the radiator contained a greaternumber of steam-chambers, to such other of the upward-conducting pipesas is deemed advisable. This valve consists of a bar, Z, mounted in waysformed by the lugs m a, cast upon the base A within the chamber 1), thebar being closely packed to prevent leakage by the strips 0. Thevalvestem 19 projects through the base A, andis pro vided with themanipulating];nob E. The bar Z is formed with openings 8 s, which may bebrought into register with the pipes d, as shown in Fig. 1, or the barmay be moved to close the entrance to the pipes, as shown in Fig. 2.

It will be observed that the arrangement of valve Z and chambers a andb, with their connecting-pipes, is such that when the valve is closedthe normal course of steam-circulation and water-drainage in thatportion of the radiator is not in any way changed or disturbed, and thatthis active portion of the radiator when thus cut off from the rest istherefore as complete and perfect in all its parts as the whole is whenthe valve is open.

Radiators constructed as above described provide for a perfectcirculation of the steam through all the pipes, provision being made forthe removal of every drop of condensed water from each pipe andsteam-chamber immediately upon its condensation, and eonse- .quentlythere is no noise.

water or air which would interfere with the equal distribution of theheat, and in my construction every portion of the surface of every tubeis a heat-radiating surface.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Ina radiator, the combination of a water chamber provided with aseries of cups pro- 10 jecting upward from its bottom, a series ofsteam-chambers above the water-chamber, and provided with a series ofeductiontubes projecting into the cups of the water-chamber, and aseries of steam-tubes projecting from the several steam-chambers, theseries of tubes of one chamber being connected to the series of tubes ofthe adjacent chamber, substantially as herein shown and described.

2. In a radiator consisting of a base having formed therein a series ofseparate steamchambers arranged side by side, and several series ofpipes connecting said chambers, each chamber being connected to the nextadjacent chamber by a series of pipes, a sliding bar arranged to slidewithin one of said steamchambers and to cover the ends of said series ofpipes, and having a series of perforations which register with saidseries of pipes,whereby steam may be admitted to a part or all of thechambers of'the series, substantially as specified.
